VIRILE SENTIMENT 63 



two alternative characters exhibits itself in the hybrid, 

 and the other does not. We may speak of the 

 character which thus shows itself to the exclusion 

 of the other as the Dominant one, and the one which 

 temporarily disappears as the Recessive character. 



When these hybrids are mated with each other, 

 or are mated back with either of their two aprents, 

 or with individuals like their parents, blackness and 

 albinism separate out again in this second generation. 

 But we know from experiment that all the black 

 individuals of the second generation are not alike. 

 This is a very important fact, and its social bearing 

 we have already glanced at (pp. 60 and 61). Some 

 are pure black individuals, and others are hybrids ; 

 the one carries blackness only, and the other both 

 blackness and albinism. And there is a certain 

 proportion in which these types appear when hybrids 

 are mated inter se. It is one pure black, two impure 

 blacks, and one albino. 



If the pure blacks be bred with each other, only 

 pure black individuals are produced in the offspring. 

 The dominant character breeds true. If the albinoes 

 be mated with each other, only albino offspring are 

 produced. The recessive character also breeds true. 

 But if the impure blacks be bred together, then the 

 offspring again consists in this third generation of 

 different individuals in the proportion of one pure 

 black, two impure blacks, and one albino. The 

 hybrids do not breed true. 



Now a moment's thought will show us that we 

 cannot explain these facts on any assumption of
